Former New Hampshire Gov. John Sununu, a Romney campaign co-chair and top surrogate, railed against President Barack Obama today after last night's debate, telling MSNBC's Andrea Mitchell that the president was "lazy and disengaged."

"What people saw last night was, I think, a president that revealed his incompetence, how lazy and detached he is, and how he has absolutely no idea how serious the economic problems of the country are," Sununu said on MSNBC's "Mitchell Reports."

Mitchell was taken aback.

"Governor, I want to give you a chance to — to maybe take it back," she said. "Did you really mean to call Barack Obama, the president of the United States, lazy?"

"Yes. I think you saw him admit it the night before when he delivered the pizzas" to the Obama campaign's Nevada field office, Sununu said. "He said, 'They're making me do this work.' He didn't want to prepare for this debate. He's lazy and disengaged."

Obama spent three days preparing for the debate in Las Vegas. On Monday, he took a break and visited the Henderson, Nev., field office.

"Basically they're keeping me indoors all the time. It's a drag," he joked, according to a pool report. "They're making me do my homework."
